Given the dysfunction that now prevails in Wikipedia, and the fact that effort on Wikipedia is anonymous, unrecognized, and unrewarded, the most appropriate course for a scientist or other expert is to avoid all stress inducing aspects of the project. They should treat the project as a fun hobby and stay away from potentially stressful activities such as resolving disputes or enforcing policy.
These hobbyist-experts ought not to concern themselves with the success or failure of Wikipedia. Perhaps Wikipedia will squander the labor of talented volunteers. Perhaps Wikipedia will alienate knowledgeable contributors by giving credence to fringe views. Perhaps Wikipedia will dissipate the good will of readers as inferior and biased articles increasingly predominate. Such matters are of no consequence to the hobbyist-expert.
Be a WikiSloth. Spend time with your family. Write real papers and real articles in the real world. On Wikipedia, enjoy yourself.
